To (.IZZ i12/wm it may concern lie it known that l, llZILLrAM E. Davis,a citizen of the United States oi' America, and a resident of Newlipswich, county of Hillsborough, State ot New Hampshire, have inventedcertain new and uset'ul improve ments in StiapCla1nps, of which thefollowing is a full and clear speciication.

rilhis invention relates to a strap clamp of the buckle type, the objectof the invention being to provide a secure holding means for the strapthat will not require that the strap be perforated or otherwiseweakened, as more fully hereinafter described.

ln the drawing-Figures l, 2 and 3 are, respectively, a front elevation,an edge elevation, and a vertical longitudinal section ot the preferredtorni ot my device, the sectional view being taken on the line 3-3 of l;and Figs. t and are, respectively,

horizontal sections on the lines 4.-4: and

5-5 et Fig. l.

Referring to the drawing annexed by reference characters, a designatesthe main plate of the buckle which at its lower end is curled to form aneye Z) for connection to the loop c, the latter being adapted to beconnected to one end of the strap or to a suspender attachment, etc.'lthe upper fend of the plate is provided with a transverse slot CZ, andthe bar e at the upper edge ot this slot has its front edge inclinedupwardly and forwardly, as at f.

il pivot g is mounted rigidly on the ears ZL located at the side edge ofthe main plate,

and pivotally mounted upon this pivot is a plate i whose upper edge jbends toward the inclined face j, the upwardly extending part ot theplate being sutliciently long to bring l the edge of the bent part jagainst the inclined face ,-f when the upper part ot the plate is swungtoward the main plate. rllhe lower part in ot the pivoted plateterminates adjacent to a staple Z projecting trontward ltr-om the mainplate a. rlfhe tree end ot the strap is passed through the slot eZ,thence between the inclined tace f and the edge ot part and thence downunder the staple Z, so that when the strap is 'drawn taut the actionwill be to pull the upper part of plate i inwardly and thus clamp thestrap securely between the edge 7' and the inclined tace fp The tree endott the strap will be prevented from swinging outwardly tar enough to bepulled between the'parts y' and f by means of the staple or loop Z, andthe free end of the strap will be clamped in this loop Z by the outwardswinging tendency ot the tail-piece Z6, the lower edge of which engagesthe inner faceof the strap and presses the strap against the cross-barot the staple. llt will be observed that the more the nstrap is pulledon the tighter will be the clamping action; at the same time, it will beobserved that if the tree end ot the strap is held by one hand thebuckle can be slid upwardly on the strap by exerting a little torce,since by upwardly pushing on the buckle, there is exerted a tendency toease up on the clamping action between the parts ,t and Having thusdescribed my invention, what ll claim is:

A strap clamp consisting ot a main plate having a transverse openingacross its upper end, thereby forming a bar across said upper end, aclamp plate pivoted on the iront tace of said main plate and having itsupper edge adapted to clamp the strap against the front tace of theaforesaid bar and having its lower part depending below its pivot andlying in front of the main plate, and a loop projecting forwardly tromthe iront face ot the main plate adjacent to the eX- tended lower end ofthe pivoted plate so that when the upper end of the pivoted plate ispulled by the strap against said bar the eirtreme lower end of the platewill swing outwardly and bite the strap against said loop.

ln testimony whereof ll hereunto atlix my signature.
